<p>The arrangement has a connecting unit i.e. adhesive attachment (5), for fastening to a retained tooth, where a closed coil spring (1) is hinged to the tooth in a bending-stiff manner. A deflecting point of the closed coil spring is rigidly anchored to the connecting unit. The closed coil spring is connected with the connecting unit in a torque-transmission manner. The closed coil spring is formed as a steel spring with definite spring constant. The closed coil spring exhibits an eyelet (6) at its free end, where the eyelet is fastened to an arc.</p> |
